Hello Fluiders,

I simulated 3 Domains as shown in the picture. i know it's kinda funny cause it doesnt simulate anything useful. Anyways the problem is interesting. The two Domains of both ends are stationnary, the one in the middle rotaes. Now actually the mesh is rotating but since there is nothing in that middle section that could make the fluid rotate it is quite interesting to see that the streamlines show a rotation in the middle section. Does anyone have an idea what that is due to?
